CNMG120404 AH6235 Tungaloy turning insert — ISO rhombic grade for stainless-steel turning

CNMG120404 AH6235 is an ISO-standard rhombic indexable insert designed for external and internal turning applications where improved chip control and resistance to edge breakage are required

• PVD-coated carbide for toughness
• ISO rhombic CNMG geometry
• 0.4 mm nose radius for strength and finish

Reliable cutting in demanding stainless-steel applications

The PVD coating combined with a carbide substrate in this grade delivers increased toughness for machining stainless steel and other difficult-to-cut alloys. The specially developed AH6235 grade is intended for operations with a higher risk of edge chipping and for interrupted cuts; this results in fewer unexpected tool changes and a steadier production rhythm. The coating improves heat resistance and reduces adhesion, while the substrate maintains the cutting edge under varying cutting conditions.

Geometry tuned for stability and surface quality

The rhombic CNMG form with an 80° approach angle and a 0.4 mm nose radius provides a balance between edge strength and surface finish. The geometry reduces vibration in less rigid set-ups and helps distribute cutting forces across the edge, which supports consistent dimensional accuracy. Because the insert follows ISO dimensions, it is straightforward to match with standard ISO turning holders, ensuring predictable fit and repeatable clamping behaviour.

Cost-effective design with secure mounting

A double-sided configuration and central cylindrical hole allow straightforward indexing and reliable clamping; the insert’s 4.76 mm thickness contributes to rigidity at the cutting zone. The reversible design extends usable life per insert and simplifies inventory management, delivering a favourable cost-per-edge ratio for batch and serial production. Selecting the correct chipbreaker and match of grade to workpiece material is essential to maximise economy and surface integrity.

Easy integration into production workflows

This ISO insert is intended to be used as part of a complete system: the insert, a compatible external holder or boring bar, a suitable clamp or shim, and the appropriate fixing screw. Compatibility is determined by form, relief angle, tolerance class, fixation, size and thickness; choosing the correct combination enhances process security and reduces set-up time. Technical data such as the designation and SKU help to ensure the right part is ordered and fitted to the holder.

FAQ

Which materials is this insert intended for?
The CNMG120404 AH6235 Tungaloy turning insert is formulated for stainless steel and similar alloys; the tough AH6235 grade helps resist edge breakage in interrupted and demanding cuts.

How is compatibility with holders determined?
Compatibility depends on the insert form, relief angle, tolerance class, fixation, size and thickness; CNMG120404 follows ISO dimensions so it fits standard CNMG holders when matched correctly.

Does the insert have a coating and what is its purpose?
Yes — the AH6235 grade features a PVD coating on a carbide substrate to improve heat resistance and reduce adhesion, supporting longer edge life under thermal load.

What mounting style does the insert use?
The insert is supplied with a cylindrical hole and is designed for secure clamping in ISO-compatible holders; the double-sided format facilitates indexing and economical use.

Is this insert suitable for interrupted cuts?
The AH6235 grade is specifically intended for tougher conditions, including interrupted cuts and operations with elevated breakout risk, providing improved reliability.
